Cylinder and Cone
![Cylinder Cylinder is a body of rotation. We have a rectangle and we rotate it around its side. We get cylindrical surface and two circles, called bases of cylinder. H is height of cylinder. R is its radius](https://fsd.videouroki.net/html/2018/12/13/v_5c122515e42ed/img1.jpg)
Cylinder
Cylinder is a body of rotation. We have a
rectangle and we rotate it around its side. We get cylindrical surface and two circles, called bases of cylinder.
H is height of cylinder. R is its radius
![Cone Cone is a geometric body that is formed when a rectangular triangle rotates around its cathetus. H is height,R is radius and l is generatrix of cone.](https://fsd.videouroki.net/html/2018/12/13/v_5c122515e42ed/img2.jpg)
Cone
Cone is a geometric body that is formed when a rectangular triangle rotates around its cathetus.
H is height,R is radius and l is generatrix of cone.
